Grizzly has the hard earned experience to mix the rip

The Grizzly name is synonymise with taking on virgin ground and layering overgrowth into the essence of what will become new pasture or cropping ground and more recently digging deep and mixing soil for higher yields

Grizzly Engineering has amassed almost 40 years’ experience in making tough machines for Aussie farmers.

And with that time comes a lot of experience and feedback from satisfied operators and according to Grizzly that gives them the advantage over many other machines available on the market today.

As one of Australia’s leading disc plough manufacturers, Grizzly Engineering has learnt over a long history of what gets the best results for the least amount of inputs.

At the end of the day Grizzly believes it is a holistic and systematic approach that sees the most successful farmers making more money while pushing further and further ahead.

Deep Ripping has been a huge part of the systematic approach Grizzly have offered farmers for almost 40 years.

It is an important part of taking the health of any farm into consideration, to ensure the harvesting of the most moisture, and in turn grow the best crops and fodder possible.

Breaking hardpans, for better root growth and access to moisture are all advantages gained from deep ripping.

While this is deep ripping explained at its most basic level – there are also things to consider, and plan for such as pH levels of soil, hard pans, non-wetting soils, natural soil layering and much more.

As for controlled trials with deep rippers, there have been many varied results dependent on rain fall, natural variability and the list of variables goes on.

However, when this is posed as a question “Was deep ripping beneficial and did you achieve a return on investment.” The answer is yes across the board.

Importantly, in addition to the immediate financial benefit, there is the ongoing financial benefit as well. As the ongoing soil health and reliability of a farm’s greatest asset, the soil, is improved.

With many points to consider, there are times and conditions where deep ripping on its own isn’t the answer. To maximise results, soil may need more than just deep ripping.

This is why Grizzly developed the Deep Discing legend, the TINY460 to work to a depth of 300mm (12-inches) plus to not only bust open hard pans but to efficiently mix down to that depth as well.

This poses the question, when and why would someone want to mix 300mm (12-inches) plus.

The simple fact is where there is acidification in the soil and growers want to bring pH back to an optimal range.

Or there is non-wetting soil present, It is necessary to mix the soils and work the lime and clay and non-wetting through the profile to get the desired result.

Grizzly says they have seen some really promising data come out to prove that this works and working it with a desired tool such as the TINY460 will often achieve the best results.

The interest in Grizzly to offer an offset disc to work deep came about when farmers came to them wanting to achieve improved outcomes.

These farmers witnessed the limitations with inclusion plates on tines such as trying to get large quantities of topsoil to fall in behind the tine.

They realised that the small amount of material falling in behind the tine simply wouldn’t achieve what they needed from the process.

While there was a small quantity of top or spread material finding its way down behind the tine the overall effectiveness was limited.

As an industry leader, Grizzly says it has looked at the theory of using inclusion plates both from a theoretical position, trials and evidence.

Grizzly determined that all things point to this approach as being substandard to achieving the level of soil movement required.

Grizzly states that ultimately if you want to get material down to the root zone on a consistent and reliable level and have it throughout your profile then there needs to be some proper mixing take place.

Grizzly has been investing heavily in scaling up their range over the past few years to meet grower demands of mixing soil to a depth greater than 300mm (12-inches).

Grizzly cites new research that shows the benefit in deep mixing in some soil types where certain outcomes are desired.

While current planting practices are proof that the uptake of technology has many advantages, as with all things there are some side effects which are starting to show up.

And without intervention all pointers are saying things will get worse. “We all know farming isn’t a one-size fits all system, we need to get to know our soils and look at what our soils are telling us to help our soil remain healthy and productive.

“We have helped farmers turn pretty ordinary country into high yielding healthy soils,” says Grizzly marketing manager and company director Skye Poltrock.

“Whether it be attributable through soil types, crop selections and rotations or chemical use, many no-till farmers are seeing pH levels in the root zone drop.

“It is often to a level where their soils are telling them they need to do something to address the issue.

“That’s where the Grizzly TINY460 is coming into their farming program,” adds Skye.

With the help of forward-thinking agronomists and soil mapping technology, some growers spread lime on the surface to mix through the profile.

While others are choosing to simply mix the soil with nothing added and some are mixing clay through their sands to help manage the very costly issue of non-wetting soils.

Whatever the issues, Grizzly has developed their machines to mix soil evenly through the profile of a working depth to greater that 300mm (12-inches) in the most efficient way available.

Depending on requirements, soil types and scale, Grizzly has models available to mix from 200mm (8-inches) through to 300mm (12-inches) plus.

Grizzly adds, these machines are incredibly easy to use, set up, maintain and the need to pre-rip or avoid the odd underground obstacle isn’t required.

Designed and manufactured in Australia, Grizzly is a family owned company, with an emphasis on building a quality product and relationships with customers and dealers.

The company’s success is on the back of building high quality machines that allow growers to achieve improved results from cultivation applications and that’s how developments such as Grizzly’s TINY460 came about.

Grizzly is quick to point out there are many newcomers into the market that claim to have reinvented the wheel when it comes to deep ripping and mixing soils.

But Grizzly asserts the data and anecdotal evidence often doesn’t support the fancy graphs and outlandish claims and catchy marketing slogans that these newcomers are making.

Grizzly is an Australian owned company with access to parts, service and support located around Australia.

Grizzly Deep Digger works down to 550mm (22-inches)

Grizzly’s Deep Digger runs curved shank 32mm Biss80 tines and works down to 550mm (22-inches)with a 660mm (26-inch) underframe clearance. Models are configured from one to 15 tines with working widths from 0.5 to 7.5m (1.6 to 25ft)

Grizzly Engineering is renowned for its deep tillage machines both in static tine deep rippers for getting down as deep as 550mm (22-inches) and for general and deep discing machines.

The Deep Digger is ideal for getting in deep and breaking up the hard pan and all soil types.

Its curved tine makes it efficient to pull and achieves full break and lift of the profile to ensure maximum results. Grizzly’s vast range of ripping machines also includes straight shank rippers for farmers wanting that style of machine and optional hydraulic auto reset shanks for added operator convenience.

Grizzly has so many different options for ripping machine they are bound to have what you require. Optional and layout for 59 to 441kW (80hp through to 600hp) so all sectors of the agricultural industry.

Grizzly also specialise is making rippers adapt to suit Controlled Traffic Farming (CTF) and can custom make with tine spacing’s and machines widths to match any operation.

Improved water harvesting and water holding capacity of soil will allow plants to access moisture and nutrients. In ground that is prone to water logging – ripping is also known to improve the soil structure.
